Yeah honestly? This is what a big part of it comes down to for me. I wouldn't call ATB inherently a bad system, there's ways to make it interesting like Chrono Trigger, or apparently Grandia. But the games Omi has been playing from FFIV to FFVIII don't really do anything particularly interesting with it beyond the occasional "WATCH OUT THE BOSS WENT INTO COUNTER STANCE, BETTER WAIT 20 SECONDS BEFORE YOU DO ANYTHING".That's accurate, yes. As mentioned upthread, Chrono Trigger does interesting and useful things with the ATB system. There may be other, further uses for ATB that make it a good choice for the combat system.
Final Fantasy, as we've seen up until now, just doesn't do any of it.
I'd much rather play a refined turn based system or something else by comparison. Etrian Odyssey is a game where everyone selects their actions then goes the way FFI to FFIII work, but implements things like buffs and debuffs lasting a specific amount of turns that you can check, and not being able to stack more than 3 of each. Bravely Default is basically "What if Final Fantasy V but modernized and turn based", but also the Brave/Default system lets you go into turn debt (or save up turns) for extra moves, doing things like "My character takes 4 turns RIGHT NOW but then can't do anything for the next 3 turns", and that's not even getting into the BP-gain combos you can cheese with using some class combinations. That's just off the top of my head, there's sure to be other examples of taking a classic turn based system and iterating on it to be more exciting (or iterating on ATB to be more exciting, or even just entirely different RPG combat systems).
